As even spacing between underwater lights on large superyachts is essential for the best effects, the use of the QT167 becomes a vital product in underwater lighting design and as such has been designed to compliment a complete underwater lighting system for areas of the hull where access is restricted, such as in a water or fuel tank or where rear access is unavailable.

The light unit is fitted from the outside of the hull and secured into the cofferdam. The cabling is then routed through the rear of the cofferdam and ran to the external driver.

The QT167 has an identical light output to the QT75 and is available in single color or color change technology utilizing the entire color spectrum, which produces over 16 million color choices to create just the right mood.

With complete Lloyd’s Register Approval on all components, the QT167 has completed several underwater lighting system on some of the largest and most prestigious Superyachts in the world.

We offer a bespoke design service tailored for each individual hull so contact us today for a one to one consultation.

QT75 and 167 Installation on M/Y Anodyne


25 years ago we made the very first underwater light for a ground breaking Superyacht in Europe. A quarter of a century later those same lights are still working perfectly and is testament to our ability in making the best products in the market. We've NEVER had a light fail due to water ingress. We have kept our overheads low and our team small in order to stay efficient and competitive and that's why we are amongst the small number of trusted companies in the industry.


All of our products are designed and made in house. We use local specialized sub contractors when needed and have and never will 'farm' our production or design out to companies in China or Asia. We believe in first principles and are not willing to cut corners in order to save a dollars. 


All of our products are made from the very highest grade Aluminum, Bronze and 316L Stainless steel. Not only is this essential for strength and longevity but aids heat dissipation and structural strength. Although plastic housings offer a vastly reduced cost benefit, this saving is not in the customers best interest and therefore not in ours.
